Based on the public IP addresses shown, which addresses can be assigned to an Azure Firewall Premium (FW1)?

Azure Firewall Premium requires a Standard SKU public IP address. IP1 and IP2 are Standard SKU public IP addresses, making them suitable for assignment to FW1. IP3 is a Basic SKU public IP address, which is not supported by Azure Firewall Premium. IP4 and IP5 are public IP prefixes, not individual public IP addresses. While public IP prefixes can be used to create Standard SKU public IP addresses, the prefixes themselves cannot be directly assigned to a firewall. Therefore, only IP1 and IP2 can be assigned to FW1.
